It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 "Emergency Vehicle Sirens". However, unprotected exposures of a sufficient duration to properly located siren speakers can still create a risk of hearing loss.

It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.

Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.

A wide range of features comes standard with Federal Signal's PA300 series siren. Included are five basic siren tones, TAP II (horn-ring transfer), PA, radio rebroadcast, and air horn sound with siren override. TAP II allows for effective intersection traffic clearing capability without having to remove your hands from the steering wheel or your eyes from the road.

The PA300 siren includes a permanent noise-canceling microphone that produces high quality voice reproduction without feedback squeal, and the microphone’s push-to-talk switch will override any siren tone for instant PA use.

The PA300 series of sirens can provide either 100- or 200-watt output and will meet or exceed SAE J1849 and Class A requirements for sound when paired with a Federal Signal high-power speakers.
